    I thought at first it was silica molds, seems quite clever. I assume the funnel/filter allows to skip the skimming process, or to complete it but what is it made from, stainless steel? People advice against steel crucibles as it can cause contamination, but wouldn't such a contraption cause trouble? Or is it something more "exotic" like titanium, tungsten ...?
